I try to do fall pruning when leaves drop. It is also the time i wire trees. After that i place them in the greenhouse so they don't stay too wet. In my opinion leaving them in a soaked soil medium for a few months followed by frost is not beneficial. I used to tuck them away in a dark shed, it had less fluctuations of temp and was better in my opinion, but it took more time. The left row is ready until spring, the two other rows still need work. Not ready yet...
